Media agnostic display for wi-fi display

Abstract

In techniques of this disclosure, a source device establishes a connection to a sink device. The source device performs a service discovery using a real time streaming protocol (RTSP) mechanism. In some examples, the service discovery provides media agnostic display attributes of the sink device to the source device and a connection type between the source device and the sink device. The source device encapsulates application data at the source device based at least in part on the connection type. The source device establishes a streaming session between the source device and the sink device. In the streaming session, the source device sends the encapsulated application data to the sink device.
